ARTHUR G. BAGNALL, OF CLEVELAND, OHIO.

SASH-CORD ATTACHMENT.

To all whom it may concern:

Be it known that I, ARTHUR G. BAGNALL, a citizen of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented a certain new and useful Improvement in Sash-Cord Attachments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to windows and especially to the means for attaching-the sash cord to the slidable sash, and has for its object the provision of a sash cord attachment which shall be susceptible of cheap and rapid manufacture and easy installation, and shall permit the ready and convenient removal of the window sash for purposes of cleaning or repairing.

A further object is the provision of a -de vice which shall shield and cover up the unsightly sash cord, and shall hold the sash cord in a fixed position after the removal of the sash so as to permit the ready replacement of the same.

Further objects and advantages of my invention will be made apparent from the following description and claims.

One embodiment of my invention is illus trated in the drawings accompanying and forming a part of this specification, in which:

Figure 1 is a partial elevation of a window equipped with my improved sash cord attachment; Fig. 2 is a detail perspective view looking upwardly at the lower part of a partially raised sash and showing a portion of the casing and guide; Fig. 3 is a perspective view of a part of the guide showing the runner or slide in locked position; Fig. 4 is a similar view showing the runner or slide in slidable position; Fig. 5 a perspective view of the slide showing its attachment to the cord; and Fig. 6 a development of the blank from which the slide or runner is manufactured.

Describing the parts by reference characters, 1 indicates the sill of the window, 2 one of the side members of the casing and 8 and 4 the slidable sash. I have illustrated my attachment in connection with the lower sash only, though it is obvious that the same can be and will, in fact, be used in connection with the upper sash in exactly the same manner. Each side member of the casing is formed with a guide-way in which the sash is slidably mounted, according to the usual Specification of Letters Patent.

construction, and a vertical groove 6 is formed therein to receive the guide or channel member 7. This member is preferably made in the form of a rectangular metallic tube having in its front face a longitudinal slot 8 and is of a depth to fit snugly in the groove 6, and extends substantially the full height of the casing as shown in Fig. 1. The usual pulley is let into the upper end of the side member and a sash cord 9 is concealed in the guide, passes over the pulley, and is attached to the usual counterweight 10. The lower end of this guide is partially cut away as shown at 11 so as to form a pair of abrupt shoulders 12 for a purpose hereinafter referred to. Carried inside this guide and fitting snugly therein is the runner or slide 13, which is preferably stamped from a single blank 13 and has an upper tubular portion closely embracing the cord 9 and a lower flat extension 1 1. The tubular portion is preferably made by bending up and around the cord the lateral ears 13 which are integral with the blank, and the thickness of the metal is preferably substantially equal to the depth of the cutaway portion of the guide, as shown in Fig. 3. The cord engaging portion of this slide or runner is provided with inwardly projecting tongues or prongs 15 which may be conveniently punched from the blank itself and serve to grip the cord and hold it securely in engagement with the runner or slide. The extension 14- is provided with a perforation 16 in which is pivoted a button 17 which has a width substantially equal to the width of the groove 6, a thickness sufficiently small to permit it to slide freely along the slot 8 when turned into vertical position as shown in Fig. 4, and a length to cause it to extend a substantial distance into the path of the sash 3. This button is preferably made of brass or malleable iron and has a stud on its end which is inserted through the perforation l6 and upset so as to hold the button securely but rotatably in place. The rear end of the butt-on is otherwise smooth and square so as to form a solid seat against the extension 1 1. The lower end of each of the side rails of the sash is formed with a vertical notch or recess 18 adapted to receive this but-ton.

The operation of the device will probably be clear from the foregoing descrip tion.

The cord is entirely concealed within the guide 7 and is securely attached to the sash by means of the button 17. The sash can be raised and lowered in the usual manner, the button 17 and guide 7 cooperating in keeping the window in the middle of its guide-way. In case it be desired to remove the sash, the guide strips are removed and the sash turned downwardly to a horizontal position after which it is drawn inwardly out of the casing. The button 17 110w being turned into the position shown in Fig. 3, the cord 9 cannot be retracted to the top of the casing but is locked in position thus permitting the sash to be readily replaced. It is obvious that many minor changes can be made in detail matters without affecting my invention, for example, the guide 7 may be made in other shapes than rectangular, or the slide 13 can be made from a solid block, or can have the cord attached thereto in a different manner. Besides other counterbalancing means than the weight 10 can be employed, such as a spring either connected with the cord or with the pulley, or a chain might be used in place of the cord. All such modifications I consider within the scope of my invention so far as they also fall within the terms of the claims annexed hereto, and are not disclosed in the prior art.

Having thus described my invention, what I claim is;
